Hi Everyone,

21 page tutorial guide with lots of detailed photographs throughout explaining the complete process from start to finish for simple out-of-autoclave prepreg carbon fibre. Available to download completely free using the link below.

This guide will accompany our new Prepreg Carbon Fibre Starter Kit and will of course be followed up with a video tutorial in the not too distant future.

Please provide any feedback on this tutorial here. If anything is unclear of could be explained better (or you spot any mistakes) then please let me know; I can use your input to improve the guide for everyone and ensure that the video tutorial is spot-on.

I look forward to hearing your thoughts and particularly to seeing your results if you follow this guide yourself.

Best regards, Matt

Oven cured following at 120, vacuum only. I didn't actually debulk at all either. I was using scraps to make a sheet that I could then 3D mill into a dibber. Wanted it thick and very strong, as the plastic dibbers flex too much for my liking. Wasn't concerned about any porosity, and didn't expect it to come out as flawlessly as it did. But it's very good. No pinholes on the surface, no voids in the cross-sections where it has been milled. It is really exactly the same as a 1mm thick sheet.

Under a microscope you may find some imperfections, I haven't inspected it to that level. If I were going for perfection, I would debulk. Especially if you aren't just making a flat sheet. If there's any geometry, then debulk. Glass is also a significantly easier surface to get good results from. If you were using a composite tool, you'd be more likely to hit some porosity issues.
